Anatomical cardiac and electrocardiographic axes correlate in both upright and supine positions: an upright/supine CT study.

The correlation between the anatomical cardiac and electrocardiographic axes has been discussed for several years. Using upright computed tomography, this study aimed to reveal the relationship between the anatomical cardiac and electrocardiographic axes in both the supine and upright positions. Upright CT and standard supine CT were performed for healthy volunteers, following electrocardiography in both upright and supine position.

Dynamic aortic changes during the cardiac cycle in patients with aortic valve disease analyzed by computed tomography combined with PhyZiodynamics software.

Background: Endovascular therapy for the ascending aorta is expected in the future, but the dynamic changes in the ascending aorta are unclear.

Purpose: The purpose of the present study was to evaluate dynamic changes in the aortic cross-sectional area and examine related determinants.

Methods: The subjects included 75 patients (aortic regurgitation [AR] in 18 patients, aortic stenosis [AS] in 46 patients, and 11 controls) who underwent dynamic computed tomography (CT) prior to cardiac treatment.

Two-Year Results of a Multicenter Prospective Observational Study of the Zenith Spiral-Z Limb Deployed in the External Iliac Artery During Endovascular Aneurysm Repair.

Background: Limited data is available on the use of a polyester graft limb with a helical stent configuration deployed in the external iliac artery (EIA) during endovascular aneurysm repair (EVAR), so we prospectively analyzed the efficacy of the Zenith Spiral-Z limb deployed in the EIA.

Methods and results: Patients undergoing EVAR using a Zenith stent-graft and Spiral-Z limb deployed in the EIA were prospectively registered in 24 Japanese institutions from June 2017 to November 2017. In total, 65 patients (74 limbs) (mean age: 77.

Impact of Acute Kidney Injury on Early to Long-Term Outcomes in Patients Who Underwent Surgery for Type A Acute Aortic Dissection.

Acute kidney injury (AKI) is relatively common after cardiothoracic surgery for type A acute aortic dissection (TA-AAD) and increases mortality. We investigated the incidence and risk factors for AKI in patients with TA-AAD and its impact on their outcomes. The records of 375 consecutive patients who underwent surgical treatment for TA-AAD from October 2007 to March 2013 were analyzed retrospectively.

Surgical repair for popliteal venous aneurysm causing severe or recurrent pulmonary thromboembolism: three case reports.

Poplitealvenous aneurysms (PVA) are associated with deep venous thrombosis and recurrentpulmonary thromboembolism (PE). We report three cases of PVA. In all three patients the first sign of PVA was acute PE; in one case, the PE was recurrent.

Initial experience with proximal ligation for profunda femoris artery aneurysms: report of three cases.

Profunda femoris artery aneurysms (PFAAs) are rare and difficult to diagnose in the early stage. They are often found due to the presence of complicated conditions, such as rapid expansion, rupture, or acute lower limb ischemia. Surgical procedures such as aneurysmectomy and endoaneurysmorrhaphy tend to be technically challenging because of the patient status and the extent of the aneurysm.

[Successful endovascular repair with chimney graft technique and carotid artery bypass for ruptured aortic arch aneurysm].

An 83-year-old man with a decreasing level of consciousness was carried to the emergency room. Computed tomography (CT) revealed a ruptured aortic arch aneurysm. He was deemed a high risk candidate for conventional surgical repair.

Preservation of aortic arch branches using chimney and sandwich stent grafts.

Purpose: To share our hybrid endovascular experiences using chimney or sandwich stent grafts for acute aortic arch pathologies.

Methods: Hybrid procedures for a distal aortic arch aneurysm and an ascending anastomotic aortic aneurysm rupture were reported. Right to left common carotid and left axillar artery bypasses were located.
